Dear MARMAM community, On behalf of my co-authors, I am excited to announce the publication of our new short note in Marine Mammal Science: Impacts and Lessons Learned from the First Highly Pathogenic Avian Influenza (H5N1) Outbreak in South American Pinnipeds along the Southern Brazilian Coast Authors: Renan C. de Lima, Sérgio C. Estima, Maurício Tavares, Paula L. Canabarro, Silvina Botta, Liane A. Dias, Andrine P. da Silva, Derek B. de Amorim, Larissa R. de Oliveira Abstract: Last year, a significant outbreak of highly pathogenic avian influenza impacted the Atlantic coast following mass mortalities recorded in the Pacific. Our study details the first outbreak of this virus in South American pinnipeds along the southern coast of Brazil. We also discuss the lessons learned from managing this crisis and suggest standard practices, and areas of priority in advance of potential future outbreaks For those interested, the full text is available at: https://onlinelibrary.wiley.com/doi/full/10.1111/mms.13163 Please feel free to email me at renancdl@gmail.com if you would like a copy.
